1. A method for control assistance of a vehicle, comprising:
receiving global navigation satellite system (GNSS) signals from at least one navigation satellite;
ascertaining quality parameters of the GNSS signals, the quality parameters describing a reception quality of the received GNSS signals;
ascertaining a driving state of the vehicle based on the quality parameters of the GNSS signals by comparing values of the quality parameters of the received GNSS signals to previously known reference value clusters, each of the previously known reference value clusters including a respective plurality of reference values for the quality parameters of the GNSS signals, each previously known reference value cluster representing a respective previously known driving state, and each respective previously known driving state describing a state of the vehicle influencing a signal transmission of the GNSS signals;
displaying the ascertained driving state of the vehicle to a driver of the vehicle, or providing the ascertained driving state of the vehicle to a vehicle controller of the vehicle;
determining a signal integrity of the received GNSS signals based on the ascertained driving state and providing the determined signal integrity to a navigation module of a vehicle controller, and prompting a correction of a position determination by the navigation module based on the received GNSS signals and the determined signal integrity; and
providing a control assistance function based on the ascertained driving state;
wherein the reference values of the previously known reference value clusters are based on quality parameters of reference GNSS signals received during reference measurements, and the reference measurements were carried out for various vehicle driving states.
